Fridays become the Islamic State's event for executions, amputations and lashings in public squares, an independent inquiry conducted by the United Nations found.
In every execution, civilians, even children are being forced to watch. The corpses were being displayed to terrorise the people.
Women who do not follow their imposed dress code are being whipped in public.
Children as young as ten are brainwashed to join the rebel group.
Journalists and other media personnel are constant target.
Paulo Pinheiro, Chair of the Commission of the inquiry, said that such acts of violence constitute war crimes and crimes against humanity.
In his report released Thursday, Pinheiro revealed that even Government forces are also guilty of committing atrocities against the civilians.
The Government's indiscriminate firings of missiles and shelling of bombs into civilian residences had claimed innocent lives. At worse, evidences suggest that there were instances that civilian gatherings and hospitals were intentionally being targeted.
Government soldiers at checkpoints prevent injured civilians from getting to hospitals. Humanitarian aid, such as medical and surgical supplies, was obstructed as a weapon of war.
In Government prisons, detainees were subjected to horrific torture and sexual assault that had always led to mass deaths of prisoners.
In the months of April and May, Government forces used chemical agents in eight attacks in western Syria.
The Government's Popular Committees are also recruiting for children to participate in hostilities.
Some states were unstoppable in delivering mass shipments of arms, artillery and aircraft to the Syrian Government. While other states and individuals support the Islamic State with weapons and financial support.
"The international community's failure in its most elemental duties - to protect civilians, halt and prevent atrocities and create a path toward accountability - has been matched on the ground by an abandonment of even the pretense of an adherence to norms of international law. As can be seen today, this has grave implications for the entire region," Pinheiro wrote.
"Accountability must be part of any future settlement, if it is to result in an enduring peace. Too many lives have been lost and shattered," Pinheiro added.
